Specification of Letters Patent.

Patented June 2%, 191(1).

Application filed May 11, 1904. Serial No. 207,416.

To all whom it may concern:

Be it. known that I, Gnonon lfnnon SMITH, a subject of the King of Great Britain, residing at Easton, county of Northampton, State/ of Pennsylvania, United States of America, have invented a certain new and useful Im rovement in Asbestos- Faced Woven Fabric, of which the following is a specification.

The present invention relates to fabrics having one or more asbestos faces, and such fabrics are es eciall adapted for the man ufacture of lts or cement plants, and similar localities where hot material is carried on the belt.

The invention also has for its object the improved means for tying the plies together, irrespective of the material used.

The objects of the invention are to produce a solid fabric having a woven asbestos face woven to a cotton backing.

Another object is to produce a solid fabric formed of a plurality of plies.

Still another object is toproduce a fabric in which one or both faces will be entirel of asbestos and in which the other plies wi 1 be formed entirel of cotton or other material which will withstand strains.

Another object is to reduce the amount of asbestos necessary to tie the lies to ether.

Another object is to pro uce a fabric in which one ply can be divided from the rest without destroying or separating the remainder so that when the asbestos face wears out, it may be removed from the other plies thus leaving a perfect cotton belt.,

A further object is to producfe a fabric which may be readily s liced so that a perfect even and endless be t maybe obtained.

The accompanying drawings diagrammatically illustrate sections of fabric which embody In invention, and by means of which I attain t ese objects.

Figure 1 illustrates a section of affour ply fabric formed with three binders, which engage with every weft, a portion of the figure showing the binders omitted. Fig. 2 1s a similar view of a four ply fabric showing two binders. Fig. 3 is a view of a four ply fabric showing three binders which engage with every alternate Weft. Fig. 4 is a schematic section of a four ply belt showing the plies split and cut in making a splice. Fig.

5 is a top view of the same. Fig. 6 is a section of a four ply fabric formed with three binders and with both faces of asbestos.

In Figs. 2 and 3 the warp threads are omitted to prevent confusion.

In all of the several views like parts are designated by the same numerals and letters of reference.

In Fig. 1, a is the asbestos faced side of a belt and b the side which engages with the pulleys or other supporting means.- This fabric is shown as formed of four plies, 1, 2, 3, and 4:. The ply 1 is formed of asbestos; the other three plies being formed of cotton or other material and all of the plies are of plain weave. The upper ply 1 is formed of the wefts c, and warps (Z all of asbestos.

The three lower plies 2, 3 and 4 are formed of wefts e, e, e, and warps f, f, f, of cotton or other suitable material. All of the plies are tied together by the asbestos binders g and the cotton binders h, h, which preferably are inserted durin the weaving o eration. The asbestos bin ers 9 tie the p ies 1 and 2 together. The cotton binders h, h, tie the plies 2 and 3, and the plies 3 and 4 together, thus forming a fabric in which all of the plies are firmly tied one to another Jf and all together.

It will be noticed that the upper set of binders, war 5 and wefts all being made of asbestos, wil form the upper face 0 and upper ply l entirely of asbestos. lft will also be noticed that the asbestos binders do not extend below the ply 3, therefore, the lower face of the fabric is formed entirely of cotton or whatever material is used in connection with the asbestos. It will also be noted that a very much smaller quantity of asbestos is necessa than if a single binder were used to bin all of the plies together, and that the three. lower plies being bound together by a cotton binder the structure will ,form a complete fabric even when the asbinder yarns and Warp yarns should be of the same length, upon the fabric being put under tension, for instance, if used as a belt to drive machinery, or to convey materials, the binder yarns would be broken.

It is obvious-that the improved means for the weavingthe plies and tying the plies together, may be utilized in connection with other materials than those described. For instance, the fabric may be made entirely of cotton, if such is desired.

The invention may be modified in many particulars as to the number of plies, the particular weave, or the number and disposition of the binders, without departing from the spirit of the invention.

Several modifications are illustrated: In Fig. 2 but two binders are used, the binder g of asbestos connecting the plies 1 and 2; the binder h of cotton connecting the plies 2, 3 and 4, and therefore passing entirely through the ply 3. In Fig. 3 the binders g and h engage with every alternate pick instead of with adjacent picks as shown in the other two views.

The fabric made in accordance with this invention may be spliced with great facility. As shown in Figs. 4 and 5, the diflerent plies may be split or separated and cut dia onally and arranged so as to break joint, at z, 2', the binders being removed or cut at the point covered by the splice. The plies may be then secured together in the usual manner, preferably by asbestos or cotton stitching or binding, so that the face a will be entirely of asbestos and the face I) entirely of cotton.

In Fig. 6 a fabric has both faces of asbestos as illustrated. In this view the two as bestos binders are indicated by the characters g, g, and the cotton binders by the character h. i

' Having now described my invention, what I claim and desire to secure by Letters Patent, is

1. An asbestos faced belt comprising a plurality of plies, one of said plies being ormed of asbestos and the others of cotton or other suitable material, the several plies being connected together by a plurality of binders, one of said binders being of asbestos and the other or others of cotton, the asbestos binder connecting the asbestos ply to the cotton plies, and the cotton binder or binders tying the cotton plies together.

2. An improved textile fabric, comprising a plurality of woven plies, one at least of said plies being of asbestos and the other or others of cotton or suitable material, the said plies being joined together in weaving in such a manner that the asbestos ply or plies may be removed -without destroying the other plies.
